To get dual-head output on a recent Intel integrated graphics card, such as
the 965 GM inside my Lenovo T-61 laptop, when running Fedora 10, only one
relatively non-intuitive step is needed. The virtual desktop size must first
be increased inside
xorg.conf so that both screens can fit inside the single X
Section "Screen" ... SubSection "Display" ... Virtual 3072 1680 EndSubSection EndSection
Once this is done, you can plug in a display (say, a projector), go to the “Resolution” preferences applet, and enable the new display at a reasonable resolution. F10’s version of OpenOffice.org even has a fancy two-screen presentation mode that shows a countdown timer, the next slide, etc.
